1. A method for occluding a fallopian tube, comprising:
advancing a probe trans-cervically to a site in the fallopian tube such that a first electrode is spaced by a gap from a second electrode in the fallopian tube;
applying energy from the first electrode and the second electrode to form an area of ablated fallopian tube tissue at the site;
actuating a cutting surface coupled to the probe and being positioned between the first electrode and the second electrode to cause a bleeding at the area of ablated fallopian tube tissue wherein the bleeding facilitates adhesion of walls of the fallopian tube to provide permanent occlusion; and
withdrawing the probe from the site in the fallopian tube.
